Code Activity

This is the first version of the SR speedup feature for MariaDB 10.6.

Browse Source 
Now all galera_sr tests succeed when SR speedup is disabled
and most galera_sr MTR tests succeed when SR speedup up is enabled.
The failing tests are listed in "skipped_tests" file.

The following MTR test suite run succeeds:

(cd mysql-test; ./mysql-test-run.pl --mysqld="--wsrep_SR_store=undolog"
                 --suite=galera_sr --skip-test-list=../skipped_tests --force)
